Mann + Hummel has not only accelerated the pace of filter development, but has also influenced it at times. The employment of state-of-the art research stations combined with optimally equipped laboratories and test facilities and, last but not least, the continuous exchange of ideas with our customers has secured international success of the Mann + Hummel Group. Because we have been developing and producing superior quality filtration systems for international vehicle manufactures for over 50 years, Mann + Hummel products have set benchmark standards regarding performance assessment criteria such as separation efficiency, dirt absorbency, service life and flow resistance.
